How do you turn an int into a double?

Can we store integer value in double?
Many compilers of programming languages use this standard to store and perform mathematical operations. This code may be justified when it is executed on a 32-bit system because the type double has 52 significant bits and can store a 32-bit integer value without loss.
How do you cast a double?
Use casting to report the result as a double. For example, if the grades are 90, 100, and 94, the sum of the three numbers is 90 + 100 + 94 = 284, and the average is the sum 284 divided by 3 which casted to a double is 94.666667.
